Abstract

The constituent fields/particles of the Standard Model (“matter” fields: quarks and leptons; “force” fields: gluons, weakons and photons; Higgs boson) are described with their masses, spins and charges with respect to strong, weak and electromagnetic interactions. The change in the interpretation of the SU(N) symmetries in the history of particle physics is described up to the culmination of the SU(6) flavor and SU(3) color symmetry in the Standard Model. Separate sections deal with quantum chromodynamics for strong interactions and the Glashow-Weinberg-Salam model for electro-weak interactions. The current algebra description of weak interactions is expounded as it is still an appropriate means to organize the leptons and quarks into chiral multiplets and to understand the Cabbibo-Kobayashi-Maskawa mass mixing. A further section deals with the conceptual weaknesses of the Standard Model, its generalization to massive neutrinos, various manifestations of anomalies, and the β functions of the color SU(3), the weak isospin SU(2), and the weak hypercharge U(1) component.
